“It’s been 25 years since these two talented men put their heads together, but the fruit of their latest collaboration is well worth the wait. Continuing in the spirit of Brown Bear, Brown Bear, What Do You See?, their new book incorporates the same clean design and crisp text, but this time the action takes place at the zoo, where elephants, hippos, lions and such are asked what they hear—each answer leads to the animal on the next page, and culminates with a zookeeper who “hears” a pageful of multiracial children disguised as their favorite animals. Carle’s characteristically inventive, jewel-toned artwork forms a seamless succession of images that fairly leap off the pages, and educator Martin, ever tuned in to what children like best, has assembled a thoroughly rowdy menagerie—including a fluting flamingo, bellowing walrus and hissing boa constrictor, to name a few—imitations of whose sounds will doubtless soon be echoing in many homes and classrooms. A visually and aurally splashy work, this is a splendid successor to Brown Bear, one that no fan of that popular bruin will want to be without. Ages 2-4.”
